Thanks Tom
I used the absolute position for the menu and I can get it to overlap but there is no property to center the menu on the page. Using it also stops the sticky menu from working.
I am also battling to isolate the navigation labels as the line height is the menu height. So I change the line height and the entire menu changes.
I know enough CSS to make minor mods and I am normally pretty good at researching and making those changes. This one has has me stumped. I have wasted 2 days trying to figure it out.
